2 Claims.

The objects of my invention are, among other things, to provide a pouring nozzle of this type stamped to the required size and shape out of sheet metal, with multiple pouring lips so that the nozzle itself does not have to be located in a given relationship to the shape of the can in order to pour the contents properly. According to one aspect of my invention, the pouring nozzle may be placed in any position on the top of the can, and there will always be a pouring lip in correct position for use.

Furthermore my improved nozzle with the multiple pouring lips embodies coacting holding or locking means for the closure cap which means are not a part of the pouring lips. This factor is important since the flange oi. the pouring lip where the liquid leaves the nozzle should be as thin as possible to prevent dripping, and it has been found in pouring nozzles where the lips over which the liquid passes, and such lips are a part of, or integral with, the cap-locking devices, that it is impossible to cause the liquid to pour thereirom in a satisfactory manner.

According to my invention, the flange of the nozzle acts as a sealing surface with the crown of the cap and also cuts off the flow of the liquid when the pouring ceases, while it is entirely separate from the cap-locking means carried by the neck of the nozzle below and inside the pouring lips and inside the flow of the pouring stream.

A further object of my invention is the prov sion of a multiple lip nozzle that will be cheap to construct and of easy manipulation without instructions, and that will be compact and of pleasing appearance.

Other objects and advantages will be set forth in the following description, which taken with the drawing discloses a preferred embodiment of my improved pouring nozzle and cap.

the drawing, Fi 1 is a sideelevatio'n of a can provided with pouring nozzle and closure 6 Fig. 2 is a top plan view of the nozzle afflxed to the top of the can:

Fig. 3 is a sectional view taken on the line 3-4 of Fig. 2;

Fig. 4 is a side elevation of the parts shown in Fig.2;

\ portion of the neck ii Fig. 5 is a top plan view of the nozzle with the cap in place, the cap being partly broken away to'show the locking means for the cap on the nozzle; and

Fig. 6 is a sectional view taken on the line 6-6 of Fig. 5.

Similar numerals refer to similar parts throughout the several figures. I

Referring to Fig. 1, the can or container 1 is of any usual or preferred construction having the top 8 from which the nozzle 9 extends upwardly with the cap i I secured to the nozzle 9. As shown in Fig. 3, the nozzle 9 has the cylindrical neck H which is fitted to the upturned flange l2 formed in the can top 8 and secured thereto by any suitable means such as the solder l3.

Referring to Figs. 2-6, the nozzle 9 has three pouring lips ll equally spaced-apart above the neck II which lips are similar in structure, and a description of one of such lips will suflice for the others. My invention is not to be limited to three such lips as two or more may be used to suit the requirement.

The lips ll comprise parts of the sealing flange l8 oi. irregular contour as shown in Figs. 2 and 5 that is flat and formed with a thin edge. Such flange ii is concentric with the neck H between the pouring lips H, as shown, but projects out wardly at ll around and outside the lateral pouring recesses I1 at the pouring points of the nozzle. These recesses H are outwardly drawn from the sheet-metal forming upper enlarged (Figs. 3 and 4) with their under surfaces substantially flat to form lugs i8 on the nozzle to be engaged by the locking means of the cap. As shown in Figs. 3, 4 and 6, the sealing flange I 5 lies in a horizontal plane throughout the periphery of the nozzle 9 with a thin outer edge.

The cap it has the crown i9 and cylindrical depending skirt it from the lower rim of which are integral spaced-apart inturned locking lugs ii in number and arrangement corresponding to the number and arrangement of pouring recesses ll. In the drawing three inturned lugs 2i are shown which are adapted to engage the nozzle lugs ll when the cap II is twisted into locking position (Figs. 5 and 6). Beneath the crown is the sealing gasket 22 that engages the flange i! (Fig. 6) when the cap in is drawn down on the nozzle! as the lugs 2i slide beneath the nozzle lugs II as shown in. Fig. 6 whereby the gasket l22 eifectively seals the entire surface of the flange In use, the cap it is reversgly twisted to disengage the cap lugs 2| from the nozzle lugs 18 so that the cap lugs 2| are in alinement with the spaces between the pouring lips I; then the cap I may be lifted and removed from the nozzle 5. As shown in Fig. 2, the user may tilt the can I in any convenient way to allow the liquid to be poured from any of the three pouring lips II, the shape of which in conjunction with the recesses I1 confines the flow without any undesired lateral edge for the stream. In any case the flange l5 overhangs the locking lugs I8 in such a way that adhesive liquids such as varnish, glue or syrup can not drip down on the lugs l8 to cause the cap ill to seize or freeze on the nozzle, which is important to preclude unintentional locking of the cap to the nozzle.

In my improved multiple lip nozzle there is no strain on the sealing flange it when the cap HI is screwed home as is'the case when one lip .is used and the cap lugs engage the under side of the pouring lip proper thereby causing the lip to buckle and produce a faulty closure when the cap is screwed intoplace.

Furthermore it will be observed that the nozzle without departing from the principles of my invention or sacrificing its advantages.

I claim as my invention:

1. In a pouring nozzle, a cylindrical neck adapted to be affixed to the top of a container, the upper portion of the neck being enlarged and having a plurality of outwardly extending recesses having convex, vertically-disposed contours and substantially horizontal fiat under surfaces iormed therein, and a flat sealing surface of irregular contour lying in a single plane superposed around the top of the neck and recesses, the parts of said surface in alinernent with the recesses forming multiple pouring lips having outwardly disposed flat curved edges outside the zone of said recesses.

2. In a pouring nozzle, a cylindrical neck having an enlarged upper portion provided with spaced-apart outwardly extending recesses having convex, vertically-disposed contours and substantially horizontal flat under surfaces, and a fiat sealing surface of irregular contour and substantially uniform width lying in a single plane surrounding the top of the neck and recesses, the parts of said sealing surface in alinement with said recesses forming pouring lips having fiat curved edges outwardly projecting from the irregular contour of said sealing surface with the plane of said lips coinciding with'that of the sealing surface.
